The wind speeds increase with height. The amount of increase depends upon a number of factors, but It is often assumed that the wind speeds go up in proportion to (H₁_/H₀)^(1/7) Where H is the hub HEIGHT above ground. There is also a cut in velocity where the turbine generates no power because wind speeds too low to turn the blades. Above a certain wind speed the wind turbines are braked to prevent damage to the equipment. As you may turbine blades bigger the hub height increases above ground. Additionally, the swept area increases. To a first-order, the power generated is proportional to the swept area and the hub height. So, the short answer would be yes, but that would neglect other factors are changing as well.
